Abstract

The invention provides a tower crane. The tower crane comprises a tower body, a lifting hook, a lifting arm, a balance arm and a steel structure real-time monitoring system, wherein the steel structure real-time monitoring system comprises a sensor system, a data acquiring system, a data communication transmission system and a data analysis processing system; the sensor system comprises sensors arranged on the tower body, the lifting hook, the lifting arm and the balance arm; all the sensors are connected with the data acquiring system through an optical fiber network; the data acquiring system is connected with the data communication transmission system through the optical fiber network; and the data communication transmission system is connected with the data analysis processing system through the optical fiber network. The tower crane has the following technical effects: (1) the actual working conditions of all steel structure parts can be known, thereby providing the basis for the structure maintenance; (2) the potential damage of all the steel structure parts can be known; and (3) the health conditions of all the steel structure parts can be known.

Description

technical field [0001] The invention relates to a tower crane and belongs to the technical field of high-altitude equipment. Background technique [0002] With the rapid development of economic construction, the number of large tower cranes widely used in various construction projects is increasing day by day, and accidents are also increasing. [0003] Although there are many tower crane accidents, they can be roughly divided into the following types: (1) Overturning. ⑵ Broken (folded) arm. ⑶ Take off and break the hook. ⑷ broken rope. [0004] Since the tower body, hook, boom and balance arm of the tower crane are all important parts of the steel structure, these steel structure parts will wear, rust, deform, and bend fatigue after a period of use, which will lead to the above-mentioned Accidents happen. Contents of the invention [0005] The purpose of the invention is to overcome the shortcomings of the prior art and provide a tower crane capable of real-time moni...
